Irony can sometimes be a bit harsh.
Fencing was such a big part of my life for so long, but when I got to my late 30's the power went out of my body. It was shocking, but just true, I couldn't do what I used to be able to do when I was young and I had to come to terms with it. A lot of people go into coaching, or make their peace and fence as a veteran, but I couldn't do that. It took me a long time to grasp why because I used to coach when I was competitive, so why could I not abide it when I knew I could not compete.
The answer was not attractive. I envy the young. I cannot stand to watch them and know I am not one of them.
If you are young then take up swords, or racquets, or gloves and revel in your sinuous power. Soon it will be gone, and all you will have is memory, until something comes sliding and slipping and takes even that, and you find yourself tumbling into the night.
